Abstract: PURPOSE: To form crystals such as a single crystal in required size, a plurality of insular single crystals, a polycrystal, particle size and particle size distribution of which are controlled, etc. by shaping a nucleation surface so that nucleation density thereof is made sufficiently larger than that of a non-nucleation surface and only a single nucleus is grown selectively.  
     CONSTITUTION: A thin-film 5 enabling selective nucleation and having small nucleation density is formed onto a substrate 4 consisting of a material resisting a high temperature, and a nucleation surface 6 patterned onto the thin-film 5 and composed of materials of a different kind is shaped sufficiently minutely. The single nucleus of a thin-film material is formed only onto the nucleation surface 6 by selecting the proper conditions of deposition. The nucleus is grown while keeping single crystal structure, and changed into an insular single crystal grain 7. The insular single crystal grain 7 is further grown centering around the nucleation surface 6 while maintaining single crystal structure, and turned into a single crystal 7A covering one part or the whole of the thin-film 5. The surface of the single crystal 7A is flattened through etching or polishing as required, thus forming a single crystal layer 8 capable of shaping a desired element onto the thin-film 5.

Abstract: PURPOSE:To peel and remove an amorphous silicon compound layer from a substrate of a photosensitive material easily in a short time without damaging the substrate, by mixing a fine abrasive with a medium, e.g. air, and spraying the resultant mixture onto a used photosensitive material. CONSTITUTION:A drumlike photosensitive material 2 is rotated at about 10 r.p.m., and a fine abrasive is suspended in a medium, e.g. a fluid of air or water, and scattered from a spray gun 1 in the form of a spray 3 onto the photosensitive material 2 while moving the spray gun 1 up and down along the whole length in the axial direction of the above-mentioned photosensitive material 2. Thus, a photosensitive layer of an amorphous silcon compound is efficiently removed from the surface of the substrate of the photosensitive material 2. Alumina, glass beads, plastic, etc. may be used as the above-mentioned abrasive, and the material is selected for the hardness and grain size, etc. depending on the hardness of the photosensitive layer.

Abstract: PURPOSE: To execute positioning which is a reference for working tools, such as welding devices, with a simple mechanism by controlling a centering position on the basis of the axial center of a stationary pipe in such a manner that the upper and lower traveling wheels of a wheel frame slide and expand cooperatively in parallel. CONSTITUTION: Piston rods 16, 16 are expanded by applying an air pressure on fluid pressure cylinders 15, 15. At this time, operating rods 20, 20 journaled at their ends with sliding bodies move vertically and pull fulcrum pins 19, 19 at the terminals of the operating rods 20, 20 and, therefore, a turning ring 18 turns clockwise on the outer periphery of a rotating pipe via bearings 17. Then, even if the fluid pressure cylinders 15, 15 are not individually tuned on operation, the moving distances thereof are the turning angle of the turning ring 18 and, therefore, the moving distances are the same and the traveling wheels 14, 14 of the wheel frames 13, 13 move at the specified distance from the center of the rotating pipe and come into pressurized contact with the inside wall surface of the pipe P in contact with the circumscribing circle of the traveling wheels 14, 14.

Filed: 1996-03-04
Abstract: PROBLEM TO BE SOLVED: To intensively arrange an apparatus using a photocatalyst comprising titanium dioxide to remove a pollutant in the atmosphere along with a solar cell. SOLUTION: A photocatalyst layer 2 transparentized by sintering is formed on the surface of a transparent plate 1 composed of tempered glass and arranged in parallel to the upper surface of a solar cell 3. An ultraviolet component in solar rays functions so as to activate the photocatalyst layer 2 to oxidize and remove a pollutant in the atmosphere and the visible light component permeated through the photocatalyst layer 2 and the transparent plate 1 enters the solar cell 3 to generate electricity. Since the arranging space of the photocatalyst layer 2 and the solar cell 3 is set within the same plane and the photocatalyst layer 2 is formed on the transparent plate 1 separate from the solar cell 3, when the photocatalyst layer 2 or the solar cell 3 is deteriorated, only one of them may be replaced.

Abstract: PROBLEM TO BE SOLVED: To provide a protocol data unit(PDU) retransmission control system of service specific connection oriented protocol(SSCOP) with which processing of a PDU can be prevented from being disabled after the PDU which can not be received on the side of reception. SOLUTION: When omission of a sequence number of a received PDU is detected at a reception side 102 in a PDU retransmission control system for SSCOP as a communication control protocol consisting of a B-ISDN, a retransmission request of the PDU of the sequence number is issued to a transmission side 101. In this case, the times of retransmission request are counted by a counter, and when the same retransmission request is sent from the reception side 102 more than a predetermined number of times, the occurrence of any fault on the transmission side 101 is judged. Then, recovery processing on the transmission side 101 is started and the transmission side 101 is recovered into normal state.
